STOP AND WASTE COCK.

Specification of Letters Patent.

Patented lflarch 19, 1907.

Application filed August 13,1904. Serial No. 220.600.

To all whom, it may concern:

Be it known that I, I'IARRY J. GEURINK, a citizen of the United Statesof America, resid ing at Cleveland, in the county of Cuyahoga and Stateof Ohio, have invented certain new and useful Improvements in Stop andWaste Cocks; and I hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it pertains to make and use the same.

This invention relates to improvements in stop and waste cocks.

The object of this invention is to provide a stop and waste cock whichcan be cheaply manufactured, easily assembled, and having an arrangementof parts which will effectually prevent the entrance of dirt or otherforeign material which would impede the operation of the cock.

My invention, therefore, consists in the features of construction andcombination of parts as described in the specification, pointed out inthe claim, and illustrated in the drawings.

In the accompanying drawings, Figure 1 is a central section of a cockembodying my invention, showing the valve-plug in position to shut offwater flowing in the direction of the arrow. Fig. 2 is a section on line2 2, Fig. 1. Fig. 3 is a similar view to Fig. 2, showing the valve-plugin position to shut off water flowing in the direction of the arrow.Fig. 4 is a section on line 4 4, Fig. 1, with parts broken away. Fig. 5is a top plan with parts broken away and the cap removed.

Again referring to the drawings, 1 represents the shell of an ordinarystop and waste cock, having internally-screw-threaded openings 2 and 3,into which the pi peseotions are screwed, and also a drain-opening 4 anda valve-plug opening 5. The shell 1 is provided with the usual neckportion 6 where the valve-plug enters. The outer surface of the neck 6,near its upper end, is squared, forming flat faces 7, 8, 9, and 10, andbelow the squared portion is formed an annular flange or shoulder 18.

The valve-plug 11 is at all points circular in cross-section, and in theupper end thereof is formed the usual socket 12 for receiving the end ofthe handle or key 13, which is preferably secured therein by a screw 14.In. the valve-plug 11 is formed a passage-way or opening 15, throughwhich the water flows when the valve is open, and a vent-opening 16. Ontop of the neck 6 is arranged a cap which serves both as a dust-guardand also as a means for limiting the rotation of the valve-plug. Thiscap consists of a ring or collar 17, which is arranged to encircle theupper part of the neck 6. The collar 17 is provided with an annularinwardly-extending flange 23, which closely embraces the upper end ofthe valve-plug 11 and forms the top of the cap. 011 the inner face ofthe ring 17 is formed a flat surface or shoulder 19, which is arrangedto register with one of the fiat faces on the neck 6, according to theposition in which the cap is placed on said neck 6, and thereby preventsthe cap from turning on the neck. On the inner face of the ring 17 arealso arranged stops 20 and 21, and on the valve-plug 11 is formed a lug22, which is arranged to travel between the stops 20 and 21, and themovement of the valve-plug is thereby limited to a quarter-turn.

In Fig. 1 the cap is shown in the proper position to allow thevalve-plug to be operated so as to control the water-supply whenentering at the opening 3 and the shoulder 19 on the ring 17 isregistering with the face on the neck 6. Now if it is desired to controlthe water-supply when entering through the opening 2 the cap is removedand replaced so that the shoulder 19 registers with the face 7 on theneck 6.

It will be readily seen that the cap and the flange 18 together form aboX which completely incloses the stops 20 and 21 and the lug 22,thereby preventing dirt or other material from lodging between the stopsand the lug and restricting the operation of the valve.

What I claim is-- A stop and waste cock comprising a valvecasing havinga neck portion with two flat faces, a valve-plug arranged to fit intosaid casing and having a cylindrical portion projecting above the neckportion of the valvecasing, a cap having a circular opening to receivethe cylindrical part of the valve-plug and arranged to extend down overthe neck portion of the valve-casing and having a single flat face onits interior surface arranged to register with one of the fiat faces onthe neck portion, stops formed on the interior surface of said cap, anda lug formed on said valve-plug arranged to travel between the stops onsaid cap.

In testimony whereof I sign the foregoing specification, in the presenceof two Witnesses, this 23d day of July, 1904, at Cleveland, Ohio. In

HARRY J. GEURINK.
